I was part of a radio broadcast for Black History Month this weekend, and I found a piece of graffiti I'd never seen before in the student radio station.

"Do you always carry a camera with you?" a colleague from another department asked me recently. "I do," I told him. "If you always have a camera, you'll always see things to photograph. If you never have a camera, you might not ever see what's camera-ready." He seemed more amused than anything. I let that go.
